//! FIPS: Free Internetworking Peering System

//! A distributed, decentralized network routing protocol for mesh nodes
//! connecting over arbitrary transports.

// Name the `alloc` crate directly so the sans-IO protocol cores can spell their
// heap-type imports in `no_std`-forward form (`alloc::sync::Arc`,
// `alloc::collections::BTreeMap`). The crate remains `std`; this only reduces the
// distance to extracting the pure cores into a `no_std` crate later.
